One time I was about to fry some chips so I put the first portion in the oil and all was fine, until I tried to put the second portion in and I guess I must have dripped water from the thing with holes into the boiling oil whilst doing so because the next thing I knew the oil splashed up into the air, onto myself and on the entire surroundings.
It was painful and scary to say the least and I avoided frying anything for a long while after that.
